We propose to observe the Seyfert 1 galaxy IC 4329A, the Seyfert 1.5 galaxy MCG+8-11-11 and the Narrow Emission line Galaxy NGC 526A each for 140 ks with the RGS instruments on board of XMM-Newton. These three sources are among the brightest Seyferts in the sky. As a result high quality spectra which can reveal a complex structure of absorption lines are expected. These absorption lines document the material surrounding the nucleus. They will reveal the physical properties near the nucleus as well as the geometry of the warm absorber. In addition the differences in the spectra of Seyfert 1 galaxies willbe studied.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
